Tyrannosaurus rex (Osborn, 1905)DinosauriaSaurischiaTheropodaTetanuraeCoelurosauriaTyrannosauroideaTyrannosauridaeLate CretaceousWestern North AmericaLength: 12.3 mWhat does the T. rex say? Lacking the syrinx found in modern birds, T. rex could've growled and hissed like modern crocodilians, but it almost certainly could not have roared. Sorry, Spielberg.January 18th, 2015
